Y ASSIGNOB TO INTERNATIONALIOTOB COI- rm, OF NEW YORK, N. Y A CORPORATION OI DELAWARE SPRINGIOUNTING FOR BTUB .axmns Application am February a, 1931. Serial 10.514.3.

The present invention relates to s rin mountin for independently mountestu axles an includes, more specifically, an improved spring mounting bymeans .of which 5 the load carried by the stub axles is effectivelysprung. In order that the center of gravity of a vehicle chassis may belowered, it has been proposed to mount the wheels upon stub axles WhlCllare secured to the vehicle frame 10 independently of one another "Asuitable form of spring suspension is thus required to cushioneffectively, the vehicleloads and,

at the same time serve as an effective weight carrying and loadtransmitting member for the chassis. In order that free movement of thestub axle with respect to the frame may be rmitted, an object of thepresent invention is to provide an improved form of spring mounting forstub axles of this character 80 whereby free movement of the axle ispermitted about its pivot point, at the same time rovidin the desiredcushioning effect for the vehic e chassis.

A further object of the invention is to provide a spring mounting of theabove character which is readily manufactured and assembled and which isfully accessible and does not require a great amount of space upon theframe.

30 Further objects, not specifically enumerated above, will be apparentas the invention is described in greater detail in connection with theaccompanying drawings, wherein;

Figure 1 is a view in side elevation, showing a spring constructed inaccordance with the present invention.

Figure 2 is a plan view of the construction shown in Figure 1.

Fi re 3 is a view in rear elevation, showin -t e spring mounting of Fires 1 and 2.

Iteferrmg to the above drawings, a vehicle side frame member is shown at10 having a bracket 11 upon which is journaled an arm 12. A stub axle 13is carried by the arm 12 and mounts a wheel 14 in any approved fashion.

Upon the underside of the frame member 10, a spiral spring 15 ismounted, this ring havin an extension 16 and a mounting d a fie securedto the frame member. e

spring further has an extension 18 at the other end thereof which isadapted to engage the top of the arm 12, adjacent the wheel mountlngextremity thereof. The to of the arm is preferably formed with shou ders19 to position the extension 16 properly.

It will thus be seen that any motlon of the center of the wheel up ordown will cause the winding or unwinding of the spring and, by selectinga spring of the desired characteristics, the frame is effectively sprungupon the plurality of wheels.

It will thus be seen that each arm upon the vehicle functionsindependent] of the others and free pivotal movement t 'ereof is apermitted by the foregoing s ring sus nsion, save in respect to the cus'omng e eet of the spring 13.

While the invention has been described with specific reference to theaccompanying i drawings, it is not to be limited, save as deiinedin theappended claim.

I claim as my invention:

In combination with avehicle frame and wheel, an arm journaling thewheel, a bracket a for mounting the arm on the frame for movement abouta horizontal axis and in a vertical plane offset with respect to thevertical plane of the vehicle frame and a torsional coil springsecured-to the frame at one end a and engaging the arm at the other end,the spring aving its axis substantially parallel to the axis of the armand being mounted in such manner that vertical motion ofthe arm producestorsional stresses in the spring t coils about the axis thereof.
